` l Application led December 26, 1907.

To all whom it may concern:

lie it known that I, COULTER E. GLENN, a citizen of the United States of America, resi d at Evans City, in the county of Butler an certain new and useful Improvements in Dum Wagons, of which the following is a s ec cation, reference being had therein to t e accompanying drawing. Y

This invention relates to dump wagons, and more particularly -to a novel mechanism' y for opening and closing the drop doors or gates of a wagon.

The primary object of this invention is to provide a novel mechanism for automatically closing the dro doors or gates of a dump wagon, said mec anism being actuated by the movement of the wagon.

Another obj ect of this invention is to disense with the ordinary ratchet lever heretoore manually operated for raising the dro doors or gates of a wagon. To this end, have devised a mechanism embodying a clutch, gear wheels and levers, these elements being dis osed at the rear end of the dump he clutch is actuated by the dropping of one of the doors or gates tofx one of. the gear Wheels with relation to one of the revoluble supportingv wheels of the wagon,

`whereby the drop doors or gates can be automatically closed during the movement of the wagon, and the gear Wheel being released with relation to the su porting wheel of a wagon by the clutch being moved when one of the drop doors or gates has reached a closed position.

The arrangement and details of the mechanismwill be presently described, and then s ecifically pointed out in the appended c aims. i

Referring to the drawing forming a part of this specification, Figure 1 is a side elevation of aportion of a dump wagon constructed in -accordance with my invention, Fig. 2 isa rear end viewY of the same, illustrating the drop doors or gates in a closed position, Fig. 3 is a longitudinal sectional view of a portion of the dump wagon, Fi 4 is a perspective view of therear end o the wa on, partly broken away, Fig. 5 is a view of t e rear end of the wagon illustrhting the dop doors or gates in an open position, Fig. 6 is an elevation, partly in section, of a clutch forming part of the mechanism, Fig. 7 is an elevation of one of the clutch members, Fig. 8 is an eletate of Pennsylvania, have invented uWa vation of the ear wheel forming a part of the clutch, anni Fig. 9 is an elevation ofthe hubof one of the supporting wheels of the wagon.

In the accompanying drawings, I have illustrated a dum wagon as having-a body constructed of si e walls 1 and 2, said side walls being provided with straps 3, to the lower ends o which are hinged, as at 4, drop doors or gates 5 and 6, these drop doors or gates when closed forming the bottom of the dump heforward ends of the side walls 1 and 2 are supported by a truck 7 of aconventional forin, While the rear ends of the side walls are supported upon la bolster or axle 8, this axle .having spindles 9' and 10, u on which the rear supporting wheels 11l and) 12 of the wagon are Journaled.

The confronting edges ofthe drop doors or gates 5 and 6, at the forward and rear ends of said doors or gates, arel provided with sheaves 13, and movably mounted u on said sheaves are chains or cables 14, sai chains or cables having their forward endsvfixed to the body of the dump wagon; as at 15, while the rear ends of said chains pass over sheaves 16 revolubly ca iiied by the end and connecting with a crank 23, carried by a shaft 24, jouurnaled in the side wall 1. This shaft 24 islocated adjacent to the drivers seat 25 of the wagon, and u on the inner side of the wall 1 is provide with'a tread crank 26. The pawl 21 is normall held in engagement with the ratchet whee 20 bya spring 27 attached to the crank 23 and the side wall 1 of the wagon.

The gear wheel r9 meshes with a gear wheel -28 revolubly mounted upon the spindle 10 of the bolster or axle 8. This gear wheel is provided with two diametrically opposed openings 29, and extending into said openings are diametric'ally opposed ipins 30, carried hy a circumferentially grooved lextending forwardly without the side wall 1 `member 31.

clutch member 31, said member being slidahly and revolublymounted upon the spindle 10. 'The clutch member 31 is moved through the medium of a bell crank lever 32, fulcrumed as at 33 upon a bracket 34, carried by the side Wall l of the Wagon. vThe lever 32 carries a stirrup-35 provided with pins 36 engaging in the grooves of the clutch The opposite end of the clutch member is ada ted to engage in a notch 37 rovided there or in the end of a weighted ell crank lever 38, pivotally mounted as-at 39 upon the. holsters or axles 8. The weighted end 4() of said lever carries a hook 41, this hook normally resting upon an extension 42 carried by the hinged edge of the drplpl door or gate 6.

e bell crank lever 32 is normally held in engagement with the notched end of the ivoted lever 38 by a spring 43, said spring being attached to the ever 32 and to the axle or bolster 8. The lever 32 is provided witha pivoted depending arm 44; said arm being guided by 'a bracket 45, carried by a bolster or axle 8.

The hub 46 of the wheel 12 has its irmer face .rovided with two segment-shaped slots 47, t ese slots receiving the pins ofthe clutch member 31, when said clutch member the tread crank 26 and. moves t wagon causes the drop doors 5 andy 6` tov drop, releasing the contents within the wagon. When the door 6 descends, the extension'42 of: said door engages the hook 41, moves the lever 38, releases the lever32 and the s ring 434 of said lever moves the clutch mem Aer 31 towards the vgear Wheel 28. When the 'lever 32 ,is in this osition, the lower end of the arm 44 exten s below` the end wall 17.0f the wagon, andthe pins 30 of .grooves 47 impinge the cause the gear wheel 28 and the clutch mem- 'the clutch member 31 extend through the openings 29 of the gearwhehl `28 into the groove 47 of the hub 46. As the Wagon is m motion and the contents thereof have been deposited, `vthe webs 48 between'the pins 30 and ber 31 to rotate in unison with the Wheel 12. lhe rotary movement of the gear Wheel 28 lmmediatelyimparts a similar movement to the gear v wheel 19, ratchet Wheel 2O and shaft or drum 18; the pawl -21rece'ding over the teeth of the ratchet wheel20. As the chains or cables 14 are attached to the'shaft or drum ,18, these chains or cables will be wound upon the shaft or drum to close the drop doorsor gates 5 and'6. As the drop door or 4gate 6 is elevated, an extension 49 of said door impingesthe end of the depending arm 44, raisin said arm, and through the `medium of the ever 32 withdrawingthe pins 30 of the clutch member 31 from the grooves 47 ofthe hub 46. The Weighted lever 38 assumes its normal position by gravity and locks the lever 32 in its elevated position. LThe dump wagon is now in condition to reagain.

of the dump wagon, particularly the mechthe drop doors or gates is automaticallt)T accomphshed, without the .attention o the driver of the Wagon. This feature of my inbut expe-dites the time heretofore required to dump material from a wagon'and place 'thedwagon in condition to receive another I do not care to confine myself to the specilic arrangement of the mechanism at the rear end ofthe wagon,- as this mechanism will be arranged to be used in connection with various t es of dump wagons. I also reserve the rig t to lmake such structural changes in my invention as are permissible by the appended claims.
